: We I start driving my car from cold start up, running 40mph in 4th gear, it feels like the engine is surging or missing. It's very,very mild and goes away once the temp gage reaches mid range.

I've got that too. More of a surge than a miss. Funny thing is I've got a Talon Turbo that does the same thing for the same duration. I always assumed that the fuel map for the ECU (DME in Bavarian) couldn't handle the constantly changing temperature condition as the engine warms up.
